Tree ring width measurements from Ponderosa Pine (PIPO) trees at the Gus Pearson site in Arizona. The chronology covers 437 years, from 400 to -37 calendar years before present. Data was archived by NOAA's National Centers for Environmental Information (NCEI) World Data Service for Paleoclimatology.
Use Cases
- Reconstruct historical precipitation and temperature for Arizona using tree ring width as a proxy.
- Calibrate the tree ring chronology against known climate events within the 437-year time period.
- Analyze growth patterns in Ponderosa Pine (PIPO) to study ecological responses to past climate conditions.
Strengths
- Chronology spans 437 years, providing a multi-century climate record.
- Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Data is temporally stale, last updated in 1987, and may not reflect more recent methodological standards.
- Geographic scope is limited to a single site (Gus Pearson) in Arizona, limiting regional generalizability.
- Sample size (number of tree cores) and replication statistics are unknown from the provided metadata.
